Patented April 28, 1908.

Application filed April 18, 1907. Serial No. 368,902.

To all whom it may concern: I

Be it known that I, DAVID D. UPDEGRAFF,

a citizen of the United States, residing at Port Ewen, in the county of Ulster and State of New York, have invented a new and useful Improvement in an Eyeglass-Stud, of which the following is a specification.

This invention relates to means for securpointed out in the claims, and shown in the accompanying drawings, in which,

Figure 1 is a side elevation of my device, a portion of an eye-glass lens being shown. Fig. 2 is a section on the line 22 of Fig. 1. Fi 3 is an end view of Fig. 1.

In these drawings A represents a small block which carries the lens guard B, the

. shank of the uard being recessed asshown at B. The b ock A is centrally cut out as shown at A. The recess B extends into the block A and lopens into thecentral cut out portion A.

e end of the block is provided with a circular opening A in alinement with the recess B and also communicating with the central cut out portion.

The bridge spring C and the guard shank D are both provided with smooth perforations and extend through the cut out portion A of the block A. A locking plate E of gold or other suitable metal is also inserted'in the cut out portion A and is provided with a beveled opening E, the smaller end of said opening being upon its upper face or the face adjacent the opening A. A screw F has a head F which is tapered or' reduced to fit in the opening E of the plate E. The screw head is provided with the usual slot F The manner of assembling the parts is as follows :By means of a screw driver inserted through opening A and turning the screw to the left it is run back into the opening or recess B. shank D are inserted into the opening A and slipped over the projecting head end of the screw. The plate E is then placed in position and. the screw driver again inserted through the opening A and through the opening E into engagement with the slot F? and turned to the right. This draws the screw outwardly and seats the reduced head F in the ta erin opening E of the plate E, thus secure y locking all of the parts in position. They are removed by an operation the reverse of the one above described.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A device of the kind described comprising in combination with a-lens guard, a perforated bridge spring and nose guard shank, a block carried by the lens guard and having an opening to receive the brid e spring and nose uard shank, alocking pTate fitting in said b ock, said plate having a beveled opening, and a screw having a tapering head adapted to be seated in said opening, said screw passing loosely through the perforations of the bridge spring and nose guard shank, said screw working in the block.

2. A device of the kind described comprising in combination with a lens guard, a cutout block carried thereby an opening being formed in the block in alinement with the cut-out portion, a bridge spring and a nose guard shank extending into the block through the cut-out portion, said spring and shank having alinin perforations, a locking plate having a beve ed opening, a screw arranged withm the block and working through the openings of the bridge spring and the guard shank, the head of said screw fitting in the beveled openin of the locking late.
